This invention relates to perforating machines capable of perforating record-cards to designate variable and invariabledata.

The present objects reside in the simplifica tion of the punching mechanism heretofore devised, to lessen the energy required to select and operate the punches, tosimphfy the operation by automatically feeding record cards to and from thegpunches, and toprovide a constructionwhereby the operatormay determine, prior to theperforating operation, whether or not the card will. be properly punched to accord with thefacts'to be indicated', and to coordinate with such construe: tion a correcting device forthe rectification of errors. y In the present machine, a single series of keys corresponding to the possible index points of a column are employed and oper- 2 ated successively inaccordance, with the data to be represented by perforations. ,lDe'pression of these keys differentially control the setting of'successively selected-selector disks which are power driven to their differential 1 positions to lessen the load upon the keys.

At the termination of the key operation the setting of the various selector disksasdetermined by visible indicator wheels will represent the data to be indicated by perfo- 80 rations and at this point correction may ensue if necessary. The selector disks are adjusted individually difierent extents from'the punches and whichmayrepresent a certain number of increments of operation from a 85 starting position. The punches comprise a single line, one for each columnto be punched. Upon completion of the set-up,

an operating key isdepressed which causes the record card to be fed intermittently to'the line of punches'and a collectiverintermittent rotation-of the selec'tordisks from theirdifferentially set positions. The collective rotation of the disks is effected in increments 4 of operation and in synchronism with the step-by-step feeding movement of the record cardover the line of punches. "When'a pro iection ofeach selector disk occupies a position over a punch a perforatingoperat on 60 will result. In this manner the card will be the line 3-3 of Fig. 1.

completely perforated automatically and without, attention of :the' operator.

1 The selector disks are restored to initial start ng position after-the terminat on of the punching operation to be subsequently ad nsted in accordance with the new data to heentered. 1 By selectivemanipulation. of certain levers, the selector disksma-y be returned to their previous Qsettings insteadofitheir startingpositions thereby effecting a repetitionof the sa nedata, or what is known as .gang'punching. .A new record cardis automatically' fed froma supply hopper to the punches at the time the punched card is fed to a suitable receptacle so that the attention .ofjthe' operator may be solely devoted to the operation of the keys.

Certain otheradj'uncts are employedsuch as the. correcting device heretofore mentioned, a direct and retrogradespacing key,

all of which tend to make the operation of the machine simple and facile.

Power for driving the various mechanisms is derived from a constantly running motor 20 (Fig. 3) the drive shaft of which carries a worm 21 meshing with a worm wheel 22 to drive a shaft 23. The driving connection between a connecting shaft 26 (Fig. 2)

' and the shaft 23 comprises the worm 25 and worm wheel 24. The shaft 26 at its other end has secured to it a worm 27 (Fig. 1) in mesh with a worm wheel 28 rotatable with the element 29 of a friction clutch 2930 (see also Fig. 11). The clutch elements are normally held disengaged by a forked yoke 31 which is normally latched by a latching bell crank 32. When the latch is shifted to unlatching position a clutch spring 33 causes clutch elements 2930 to frictionally engage each other.

At the termination of a card punching operation clutch elements 29-30 are disengaged but a driving relationship is initially effected upon the manual depression of one of the punch numeral keys 34 which is operated upon the institution of a new punching operation. These keys (Fig. 2) are pivoted in the usual manner so that upon a depression of any one the coaction of the related stem with one of a plurality of cross pins 35 will shift a parallel mounted bar 36 which draws forwardly a bar 37 to shift laterally an irregular shaped plate 38 (Figs. 11 and 12) which has 2. lug extension 39 in engagement with a tail of the pawl 32 to rock the latter and disengage it from the tail of yoke member 31. hen the clutch connection is established a shaft 40 to which element 30 is secured will be driven but the extent of operation is dependent upon the key depressed.

Associated with each of the numeral keys is a rod 41 guided by a plate 42 at the end which cooperates with the key stem. The rods 42 diverge (as best shown in Fig. 2) and are guided at their other ends by a plate 43 so asto cooperate with the ends of concentrically arranged plunger operating rods 44. These rods are slidably mounted in a journal bar 45 carried by plate 43 and each rod when shifted, in turn, shifts one of a plurality of stop pins 46 slidably mounted in a cylinder 47 secured to shaft 40. lVhen the clutch is established the coaction of the shifted one of the pins 46 with a frame extension 48 during a rotation of cylinder 47 determines the extent of rotation of shaft 40 (see Fig. 12).

As a key is depressed, plate 38 will be shifted against the tension of a spring 49 (Fig. 11) and since the inner face of the upper extension of the plate is in contact with the end of the stop pin 46 which engaged the extension 48 during the previous operation, it will force said pin to its inner or normal position freeing shaft 40 for rotation. The cylinder 47 will then rotate until the pin 46 shifted by the depressed key subsequently engages the stop extension 48 thus determining the differential movement of shaft 40.

The coaction of the shifted stop pin 46 with the upper extension of plate 38 will stop the rotation of shaft 40 and since the plate 38 has been brought into the plane of the shifted pin by depression of the related key (see Fig. 11) plate 38 will then be rocked (as shown in Fig. 14) and by its 'coaction with a cam extension 50 will shift the yoke member 31 to disengage the clutch elements 29-30 whereupon the yoke member 31 will be relatched by pawl 32. This operation will occur when the plate 38 is shifted by spring 49 and is coincident with the release of the depressed key. Plate 38 will then pass over the shifted pin 46 (see Fig. 14). The plungers 44 shift the stop pins 46 through levers 51 and it will be apparent that those pins 46 which have'not been shifted will in their counterclockwise rotation about shaft 40 successively rock the rod 44 which has i been shifted. This rocking movement is effected against the tension of a coil spring 52 whichis effective to rotate and restore the rod 44 to its normal position as determined by an extension thereof with a stop lug 53.

Secured to shaft 40 is a gear 54 (Fig. 5) meshing with a gear toothed disk 55 secured to a transverse shaft 56. and splined at 57 to the-shaft is an operating pinion 58. The

shaft 56 at one end (as shown in Figs. 2

and 5) is ournalled in a bail shaped member 59 pivoted at 60 to an intermediate frame member 61.. The other end of shaft 56 carried by a frame plate 62 (Figs. 4 and 5) pivoted at 63 to the parallel frame member 64. Secured between the plates 59 and 62 is a guide bar'65 3 and 5) in which is slidably mounted a yoke member 66 the side plates of which confine the pivoted pinion 58 (see Fig. 5) so that as the yoke member is shifted intermittently under control of an escapement mechanism it will be brought into selective operation with a series of spaced punch selector disks 67. The series of disks porting shaft68 which permits an independent. adjustment of each disk without p I 82 to beshifted in. lateral alignment with the affecting the position of the other disks. When the frame comprising members 59'6265 is in the position shown in Fig. 3

the pinion 5 6 may be brought into mesh with I teeth 69 formed in the periphery of each of the disks 67 as the pinion is shifted on'shaft 56 so that a differential rotation ofpinion 58 will impart a like movement'to the disk 67 in driving engagement with the pinion. In this mannerthe disks 67 are differentially set and each held. intheir set position by frictional contact with shaft 68. An intermi ttent shifting of pinion: 58 will successively set the disks and sinceakey is operated for each card column the setting of the disks will represent the index point'designation desired in the columns to-be punched. 1

I As each disk is differentially set by the'de pression of a key a punch'selector. projection 70 -(Fig. 3) 'will bepositionedarcuately a certain distance from the head of the related one of a series ofpunches 71 arranged ina single line. If the projection 70 is stepped around in'increments in synchronism with the passage of card each projection 70 (see Fig. 6) will be positioned overthe related punch at a certain time and the'diiferentpunches will be selected for operation at differential times depending upo'nthe initialsetting of the disks 67. A perforating opera tion iseffected at thete'rmination of each step of movement resultin inthe perforation of the card at the desire points.

The carriage is impelled by the usual spring controlled drum 72 (Fig. 5) to which is secured a wire 7 8 encircling a pulley 74;. The wire 73 is secured at 75 ,(Fig. 6) to the carriage 66. Intermittent movement of the carriage is preferably secured by the .followng escapement device. .Pivoted to extension77 (Figs. 3 and 17) of the carriage 66is a pawl 78 adapted to engage with inter- 7 dental spaces of saw shaped. teeth of an escapement bar 79-. The bar 79 is vdependingly hung from a pivot rod 80 and is capable of being shifted forwardly and then rearwardly as an incident to each depression of a key. Associated wlth eachdisk 1s a column selecting lever 81 having a rearward extension adapted to coact with an extension 82 (see Fig. 17 of the pawl 78 and stop the escapement action of the carriage 66. n

When the bar79,Fig. 6, is shifted rearwardly its coaction with the vertical extension of pawl 78 will rock the same clockwise and disengage the-extension 82 (Fig. 3) from coaction with theside of the previously engaged lever 81, see Fig. 17, permitting the escape. ment drum to shift the carriage. The upper extension will then coact with the inclined edge 83,Fig. 17 ofthe notch as the bar 79 is shifted rearwardlyto permit it to, subsequentand duringthis time a spring'7 6 will rock the pawl counterclockwise to cause extension next'atljacent lever 81. As the bar 79 is restored to normal the pawl .7 8. will be brought out of engagement with thenotch in the bar permitting the carriageto again step until thepawl '82 eng ges with the side of the next adjacent lever'81. Q i e r From Figyl i it will beobservedthat as a shifted pin 46 coactswiththe upper extension of plate 38 a tail 84- thereof contacting with an oblique arm 85 v(see Fig. 15) will rock a spring restored shaft 86. Secured to shaft 86 ig. is an arm 87 contacting with apin88to shift the escapement bar 79 against the restoring-action of aspring 89. The

spring 89 is effective to restore the escape-1 ing devices all operating in a manner now to be described. Secured to the drive shaft 23 is a gear 92 igs. 8, 9 andlO) driving a gear 93 to which one element 94 of a clutch device, 94.",95 is secured. Theformer is loose on a shaft 96 but the, element 95 is rotatable with the shaft 96'and is normally'urged bya spring 97. to clutchingposition but is restrained by a lever 98. a The tail 99 of the latter overlies ata'il' 100 which is an integral extension of one of the side plates of a yoke or bail 101 loose on a rod102. V r

The arms of the bail 10'1 carryarod 103, the spring 97 being effective to urge the rod 103 into contact with a lever '10 lsecured to rod 102 and biased by a spring 105 so that anextension 106 thereof may engage a helical screw thread of a'cylinder 107 rotatablewith the constantly rotating gear 93. o This engagement'is prevented by the interposition ing of a'control'lever 108 secured to a rod 109. s The operating key 91 is a bell crank pivoted upon a'rod 110 (Fig. 2) and'is con- 7 nected to a second bell crank 111 by 'a link 112. The bell crank 111 carries a wipe pawl 118 adapted to engage an armlld secured to shaft 109 in order to rock thelatter upon I depression of the key but permit the inde pendent return 10f the latter. Rocking of shaft 109, as will be ol'iservedin Figs. 8 and 10, will permit arm v10 1 to be rocked by spring 105 permitting yoke 101 to be rocked by spring97 to. perinita clutch engagement of elements 94, 95 .tOIQlllVG shaft/96. At the same time extension, 106 will engage the screw thread and be shifted laterally along with the supporting rod 102.

Secured to shaft 96 is an eccentrically mounted disk 115 (Fig. 4) adapted to efiect a reciprocating movement of an arm 116 connected to one arm of a bell crank 117 carrying a pawl118 in engagement with a ratchet wheel'119. The latter is .secured to a gear 120 adapted to drive a pair of feeding rollers 121 (Fig. 3) through a gear train comprising gears 122, 123,, 124 to thus effect a step by step movement of a record card previously placed in feeding relation to said rollers at the termination of the preceding punching operation. As the card is stepped by rollers 121 it is fed to a pair of feeding rollers 125 which then assume the step by step feed of the record card by ratchet wheel 119 since the upper roller is geared to the lower by a gear 126. The successive rotations'of shaft 96 will therefore step the record card and simultaneously by mechanism now to be described the disks 67 will he stepped around collectively to bring them into cooperation with the punches 71.

As shown in Figs. 4 and 5 the shaft 68 which carries the disks 67 has secured thereto a ratchet wheel 127 cooperating with a pawl 128 carried by an arm 129 connected to one arm of hell crank 117 by a link 130. By this means the control disks 67 are stepped around collectively as a unit from their initial set positions to bring the projections (Fig. 3) into cooperation with the punches 71 at differential times at which instance the index point to be punched is at the punching line.

Actual perforating operations are performed by reciprocating a die plate 131 (Fig. 3) each time a new series of index points'has been positioned at the punching line. The die plate 131 is carried by a pair of arms 132 mounted on shaft 96 by a pair of eccentrically mounted disks 133 to thus effect the desired reciprocation as the card is stepped by rollers 121 and 125.

As the projection 106 (Fig. 9) engages the helical screw thread of a cylinder 107 the lever 104 is shifted laterally and along with it the rod 102 to which it is secured. At the termination of the lateral movement of rod 102 which is coincident with the last punching operation, namely, the punching of the 12 index point the rod 102 will strike a rod 1021 in alignment therewith and a conical extremity 134 thereof will rock a lever 135 (Fig. 4) to release an end of the latter from engagement with a clutch pawl 136 so that a spring (not shown) may cause the engagement of the pawl 136 with a notch 137 of a clutch disk 138 rotatable with a gear 139. The latter is in mesh with a pinion 140 secured to the drive shaft 23, which it will be recalled rotates constantly. lVhen the clutch is established the gear 141 which carries the pawl 136 will be driven andthrough a clutch pawl 142 pivoted to gear 141 will drive a notched element 143 rotatable with the gear 123 (Fig. 3) driving the rollers 125 supplementally to cause the complete ejection of the punched record card to a receiving hopper 144. 7

Referring to Fig. 8 it will be observed that the lever 104 is normally positioned at one side of the end of a guide bar 145 dependingly hung from a rod 146 so that as the projection 106 engages the screw thread the extension 147 (Fig. 9) will contact one side of the bar 145. The termination of the screw thread acts to cam lever 104 forwardly, spring 105 being then effective to restore the lever 104 and rod 102, re-engagement of extension 106 with the screw thread during the restoring movement being effectively prevented by guide bar 145 permitting the extension 106 to ride over the arm 108 and finally occupy the position clearly shown in Fig. 10. When lever 104 is cammed forwardly it will rock bail 101 and the latter will rock bell crank 98. 99 to disengage the clutch elements 94-95 stopping the rotation of shaft 96. When bail 101 is rocked to permit establishment of the clutch connection a hook 148 integral with bail 101 is drawn out of engagement with a shoulder 149 of the clutch element 95 but re-engages therewith when the clutch connection is disestablished so as to lock element 95 in its normal starting position. Pawl 136 re-engages bar 135 (Fig. 4) at the terminationof a complete revolution of gear 141 to disestablish this clutch connection.

When rollers 125 are ejecting the punched card the rollers 121 are being driven synchronously. Secured to the supporting shaft of lower roller 121 is a crank arm 150 (Fig. 2) connected to picker 152 (Fig. 3) by a link 151. The picker knife feeds a blank record card from the stack to the feeding rollers 121 which then transport the card to and under the line of punches 71.

Prior to the restoration of disks 67 to their normal positions the frame 66 carrying setting pinion 58 is shifted backwardly to clear the teeth of the operating disks. This result is effected by the following mechanism. When the operating key 91 is depressed the link 112 will rock an arm 154 (Fig. 2) and a shaft 155 secured thereto. Secured to rock shaft 155 is an arm 156 which is connected to the pinion carrying frame by a link 157 to directly shift the frame when the key is depressed. The frame is held in shifted position by a latching bell crank 158 during the time the pinion is restored. so that at its normal position it is again in alignment with the first of the series of setting disks 67.

Gear 141 (Figs. 4 and 5) is adapted to drive a gear 158 through intermediate gears 159, 160 and a spiral cam 161 secured to the gear 158. r A follower secured to the arm of the bell crank 162 coacts with the cam so that a rack extension thereof rocks a pinion 163 secured to a shaft 164.

Secured to one end. ofrock shaft 164 is a 'cam 166 (Figs. 2 and 5) adapted torock a bell crank 167 andthus actuate the holding pawl 158 to release" the pinion-carrying frame 66 1 whereby the setting pinion 58 is shifted for-.

wardly into engagement with the teeth of'the first setting disk 67.

A bevel gear 168 secured to rock shaft 164 (Fig. 2) drives'a bevel gear 169 (Fig. 16) and,

a disk 169to which is secured a pawl170.

When the tail of pawl 170 leaves pin 171 s will coact with a block 17 2 secured to the face of a gear 173 in mesh with a pinion 17 1 secured to the spring escapement drum so that the latter is thereby rewound thus causing wire 73 to positively restore the pinion carrying frame to its normal position, and when this position is assumed the latchin pawl 158 (Fig. 2 previously mentioned, isactu ated to permit pinion 58 to engage the teeth of the first setting disk 67. The construction shown in Fig. 16 permits the escapement drum to be unwound without aifecting' the shaft 164 and parts connected therewith- Restoration of the'setting' disks to; theirnormal position iseffect'ed by rotatlon of shaft 68 and since each disk a frictional contact with the shaft theywill all be restored to their normal starting points. Tothis end cam 161 is provided with a pawl175 (Figs.

4 and 5) in the plane ofa shouldered disk j 176 secured to shaft'68 so that a complete rotation of the cam wiil cause the shaft; and

disks 67 to be collectivelyrotated andbrought 1 positions as determined by a pairof notches 181 and held in the desiredfpositionuby' a springdetent plate 182 having ridges adapted to coact with the notches. ,When'alev'er 81 is adjusted to the full line position. (F ig i 6) and the frame 179 rocked, at the appropriate time it will be'clear. that the, extension 17 7 thereof will engagethe shoulder 178 ofthe related disk to determine. its startingpoint after which the extensionis removed from the disk to permit free rotation of the" latter 1 during the ,next setting .operation. For

It'will be obvious that those levers which are shifted upwardly will be ineffective to stop the related-disks 67 and they will, be

Where theterms srecord cardlcolumn and indeX points appear in' the claims, it will be understood to mean that the record card is divided into parallel columns (as illustrated in Fig. 19) each column havingnine or more diflerent positions or index points. Each index point represents a different value by virtue of its location froma reference edge of thecard so that when a perforated card is analyzed by passing it through a tabulating machine in a columnar direction, or analyzed at rest, the index points will control associated representingdevices. The term record card column containing index points is, therefore, defined as a card column containing a series of different index points having varying control functions by virtue of their differential locations in the column.

I While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art Without departing from the spirit of the invention.
